Cartoon shader

Does anyone know what causes Cartoon shader not to sometimes work? When I select it, it does not render the model as a cartoon but the default rendering. The strange thing is, I can have two figures next to each other and one gets rendered as a cartoon and the other does not.

If you mean the option in Render Settings, it affects only the Default DAZ Shader (substituting the toon version of the code). Other shaders don't have toon versions and so the setting has no effect on them.
